In recent years, an unusual spate of deadly shark attacks has gripped Australia, resulting in five deaths in 10 months.

What’s behind the mysterious arrival of this apex predator in an area where they’ve rarely been seen for hundreds of years? Are deadly encounters with tourists inevitable? To separate fact from fear, NOVA teams up with leading shark experts in Australia and the United States to discover the science behind the great white’s hunting instincts. Do sharks ever target humans or is each attack a tragic case of mistaken identity? Can a deeper understanding of shark senses lead scientists to design effective deterrents and help prevent future attacks?

Animals dance, sing, flirt and compete with everything they’ve got to find and secure a mate. For many, the all-important bonds they share as a couple are what enable the next generation to survive. But can we call these bonds love? In this look at the love life of animals, we see the feminine wiles of a young gorilla, the search for Mr. Right among a thousand flamingos, the open “marriages” of blue-footed boobies, the soap opera arrangements of gibbons, and all the subtle, outrageous, romantic antics that go into finding a partner.

Nazi Mega WeaponsSuper Tanks at 9 pm
In the quest for world domination, the Nazis built some of the biggest and deadliest pieces of military hardware and malevolent technology in history.

To them, bigger definitely meant better, and better meant more lethal. As Hitler’s grip on Europe tightened, he ordered men like Wernher von Braun, Ferdinand Porsche and Alfried Krupp to build increasingly outlandish machines and structures to realize his master plan. Creating huge terror machines, hi-tech superguns and some of the original weapons of mass destruction to control a nation, conquer a continent and win the war. This is World War II told from a new perspective. The series uncovers the engineering secrets of six iconic mega-structures, tells the stories of the evil geniuses that designed them and reveals how these structures sparked a technological revolution that changed warfare forever.

NatureSnow Monkeys at 7 pm
In the frigid valleys of Japan’s Shiga Highlands, a troop of snow monkeys make their way and raise their families in a complex society of rank and privilege where each knows their place.

But one little monkey, innocently unaware of his own lowly social rank, reaches out to this lonely leader, forming a bond with him that manages over time to warm his less than sunny disposition. It is a rare and remarkable gesture that alters both their lives. Changing seasons bring new babies to care for, a profusion of insects and blossoms to eat, family disagreements to squabble over and tragedies to overcome.

NOVAInside Animal Minds: Who’s The Smartest?
What would it be like to go inside the mind of an animal? We have all gazed into a creature’s eyes and wondered: what is it thinking about? What does it really know? Now, the revolutionary science of animal cognition is revealing hard evidence about how animals understand the world around them, uncovering their remarkable problem-solving abilities and exploring the complexity of their powers of communication and even their emotions. In this mini-series, NOVA explores these breakthroughs through three iconic creatures: dogs, birds and dolphins. We’ll travel into the spectacularly nuanced noses of dogs and wolves, and ask whether their reliance on different senses has shaped their evolution. We’ll see through the eyes of a starling in flight and test the tool-using skills of the smartest of birds, the crow. We’ll listen in as scientists track dolphins in the Caribbean and elephants on the African savannah, trying to unlock the secrets of animal communication. As we discover how researchers are pushing the animal mind to its limits, we’ll uncover surprising similarities to — and differences from — the human mind. What makes an animal smart? Many scientists believe the secret lies in relationships. Throughout the animal kingdom, some of the cleverest creatures – including humans – seem to be those who live in complex social groups, like dolphins, elephants and apes. Could the skills required to keep track of friend and foe make animals smarter? To find out, NOVA goes inside the social lives of some of the smartest animals on the planet.
